Using Power Fluctuation Testing (Simulation) Function

4.3.1 Basics

The Power fluctuation testing (Simulation) function allows you to edit and output voltage patterns
that simulate power line anomalies such as blackout, voltage rise, voltage drop, abrupt phase change,
and abrupt frequency change. This section describes the basics for using the Simulation function.
 AC/DC Mode and Signal Source
Simulation function sets the AC/DC mode and a signal source, independently from Continuous
function/Sequence function. The setting is fixed to ACDC-INT.
 Keep simulation setting file
The simulation setting is cleared when the power is turned off. To save the setting, you need to save
it in internal memory or USB memory (see 4.9).
 Step
The output by the Simulation function consists of six types of steps: Initial, Normal 1, Trans 1,
Abnormal, Trans 2, and Normal 2. Before the simulation starts, this product stands by at the Initial
Step. During the simulation, the step changes in the order of Initial, Normal 1, Trans 1, Abnormal,
Trans 2, and Normal 2. After the simulation ends, this product returns to the Initial Step and stands
by.
 Step parameter
Each parameter of Step Time, AC voltage, frequency, start phase, stop phase, trigger output, and
synchronization output can be set for each step. However, some parameters cannot be set in some
steps.
